Some distros might use old kernel source but with some latest upstream
kernel patches backported to their kernel source tree. To deal with this
scenario and avoid kernel compilation failure, use conftest to check the
existence of features against the kernel source tree which the OOT
modules are built upon and do the conditional build based on the test
result generated with the conftest tool.
Use NV_DEVFREQ_HAS_FREQ_TABLE to determine whether freq_table field is
there in struct devfreq data strcuture, and choose the correct path for
building the module.
Use tegra_wmark-specific devfreq_get_freq_range always to avoid kernel
version check and conftest check. Since devfreq_get_freq_range exists in
the devfreq-specific governor.h (e.g. drivers/devfreq/governor.h) file
instead of globabl linux kernel include header files
(e.g. include/linux/devfreq.h), conftest cannot be used to the existence
of devfreq_get_freq_range kernel function.

Commit c1fa617caeb0 ("tracing: Rework __assign_str() and __string() to
not duplicate getting the string") update the __assign_str() function
and dropped the trailing semi-colon from the definition. This is causing
the NVMAP driver build to fail because of a missing semi-colon on some
of the __assign_str() declarations in the nvmap.h header. Some already
have a semi-colon and so fix this by populating a semi-colon for the
ones that are missing. Note that there is no harm in having multiple
semi-colons for kernels that define __assign_str() already with a
trailing semi-colon.

ADSP host driver is enhanced to be multi-instance
capable and reentrant:
- Trailing unique identifier string in compatible DT property, like
"adsp", "adsp1" or "aon", is used to identify the driver instances
- Each probed driver instance is inserted into a global list, from
which the handle can be fetched using 'nvadsp_get_handle' API
(passing the above unique identifier as argument)
- Above unique identifier is also used as name for the DBFS
directory (containing files like adsp_console, adsp_logger, etc.)
- 'nvadsp_get_handle' is the only exported API; all other APIs are
accessible via function pointers within 'struct nvadsp_handle'
- APIs above maintain one-is-to-one correspondence with all
legacy APIs, with the addition of a new argument
'struct nvadsp_handle *' at the beginning
- Legacy APIs continue to be supported, but they are hardwired to
work only if the kernel probes just one driver instance
- All driver files are cleaned up to not use any global state
variables (necessary for reentrancy)

3 Use correct dev pointer in vi_channel_drv_unregister().
